Justin Bieber Fans Jam London Hotel Phone Lines

Justin Bieber fans have caused havoc at his hotel in London after receptionists at the Royal Garden Hotel received over 2,000 calls asking to be put through to the teen heartthrob's room.

According to The Sun, JB's Beliebers conjured up fake identities in a bid to convince staff to let them speak to the Boyfriend singer, using names of Justin's family and friends - with one even claiming to be his personal stripper.

A source told the newspaper: "Justin’s fanbase are relentless — they will do anything to get near him.

“The phones in the hotel haven’t stopped ringing since he arrived. Staff knew there would be pandemonium but not to this extent.”

Despite not being able to speak to Justin, the 18-year old gave fans waiting outside the hotel a flash of his ripped torso from his suite window - sending the girls crazy.

He later tweeted: “Eating a steak and gonna get a good night’s rest and relax. I hear you guys outside the hotel... and I LOVE YOU!”
